Two Phase Flow Pattern in Vertical & Horizontal Pipe(tube) 유첨, Vertical Flow와 Horizontal Flow는 큰 차이 없음. Vapor Governent Flow pattern의 경우, annular flow pattern이 안정적이며, annular with mist flow가 가장 안정적임. 더보기 Air Recirculation Air Recirculation Recirculation of air which has been heated as it crosses the tube bundle provides the best means of preventing operating problems due to low-temperature inlet air. Internal recirculation is the movement of air within a bay so that the heated air which has crossed the bundle is directed by a fan with reverse flow across another part of the bundle. Wind skirts and louvers are gen.. 더보기 Rho-V2 & Erosion Erosion : 유체의 빠른 운동에너지(속도)에 의한 장치/노즐/파이프 등의 침식, 배관에 가해지는 반복적인 충격은, 빠른 속도와 양의 충격으로 쇠를 자르는 물분사절단과 같은 원리임. Erosion의 설계 기준은 일반적으로 Rho-V-2의 Momentum 계수로 판단함. Rho V2 : - Rho V2 is typical measurement for momentum, indirectly the kinetic energy of moving fluid. - many old design, many designer focus on velocity as major factor in kinetic energy. However, nowadays designer will take into account of flui.. 더보기 이전 1 2 3 4 5 ··· 9 다음
